Maximum charging power of iphone 1 1pro.

The power of Apple's mobile phone when charging is 5w.

Other charging information: the maximum output current 1A, the output voltage 5V and the input voltage 100-240V AC when charging the Apple mobile phone.

Four stages of mobile phone charging:

The first stage: fast charging stage. From the time the charger is connected to charge money, the battery voltage is at a relatively low value, and then the voltage begins to rise rapidly. Because the current value is high at the beginning, the charging efficiency at this stage can be said to be the highest.

The second stage: with the current value decreasing gradually, the voltage increases to a certain value, and its value tends to be stable. Because the current value is low, the charging efficiency will also decrease, and finally the current value is close to zero. Due to the overcharge protection function, the charging process will stop.

The third stage: the buffer stage, the charging current is 0, but the battery is not fully charged. At this time, the voltage began to gradually decrease, when the voltage value dropped to a certain value.

The fourth stage: start the final charging stage. At the beginning of the last stage, there will be current flowing again, so that charging will continue, and at this time, the voltage value will start to rise again and rise to the peak for the second time. With the decrease of current, the battery finally reaches a full state.

IPhone 1 1Pro explanation:

1, screen:

1 1 is 6. 1 inch,1/pro is 5.8 inches, all made of glass (the latter is frosted glass), but the screen is made of two completely different materials. 1 1 Using 720P OLED screen, 65433.

2. Performance:

Both mobile phones use the strongest A 13 bionic chip, which needs to be disassembled for verification. Miracle's guess is that the Professional Edition still has more storage space. In terms of water resistance, iPhone 1 1Pro is better: Pro version can stay in water with a depth of 4 meters for 30 minutes, while iPhone 1 1 can only stay in water with a depth of 2 meters for 30 minutes, but they all reach the three-proof level of IP68.
